Parameter Legal Values Descriptions

Use ‘sector_protect’ port —

• Enables the ability to protect sectors in the EPCS/

EPCQ/EPCQ-L device from write and erase operations

with an active-high input port named sector_

protect. When this port is asserted, the IP core reads

the block protection code value on the

datain[7..0]signal and writes it to the EPCS/EPCQ/

EPCQ-L status register. To protect specific memory

sectors, you must send their block protection code to

the datain[7..0] signal.

• This option is available for all EPCS/EPCQ/EPCQ-L

devices.

Use ‘bulk_erase’ port —

• Enables the ability to erase the entire memory of the

EPCS/EPCQ/EPCQ-L256 device, including the

configuration data portion with an active-high input

signal named bulk_erase. When this signal is asserted,

the IP core implements a full erase that sets the entire

memory bits of the EPCS/EPCQ/EPCQ-L256 device to

a value of one.

• This option is available for all EPCS/EPCQ devices.

Use ‘sector_erase’ port —

• Enables the ability to erase a certain sector in the

EPCS/EPCQ memory with an active-high input signal

named sector_erase. When the signal is asserted, the

IP core implements a full erase of the sector. The value

of the addr[23..0]signal indicates the sector to erase.

For EPCQ256/EPCQ-L256 or larger devices, the width

of the addr and read_address signals is 32 bit.

• This option is available for all EPCS/EPCQ/EPCQ-L

devices.

Use ‘die_erase’ port —

• Enables the ability to erase each die in your device.

When the signal is asserted, the IP core implements a

full erase of a single die in your device. You need to

issue the erase die operation twice for EPCQ-L512

device and four times for the EPCQ-L1024.

• This option is available for Arria 10 devices with

EPCQL-512 and EPCQL-1024.
